Distributed sequence number generation?

Question

I\'ve generally implemented sequence number generation using database sequences in the past.

e.g. Using Postgres SERIAL type http://www.neilconway.o

It can be done with Redisson. It implements distributed and scalable version of AtomicLong. Here is example:

Config config = new Config();
config.addAddress("some.server.com:8291");

Redisson redisson = Redisson.create(config);
RAtomicLong atomicLong = redisson.getAtomicLong("anyAtomicLong");
atomicLong.incrementAndGet();
